[EX Q]: Article: Pottery is the name given to all kinds of useful or artistic objects made from clay. Pottery can be plates or water pots or baskets. Pottery can be large or small, fancy or plain. Pottery is part of the large family of ceramics .Ceramics are synthetic materials. For example, bricks and tiles   are both ceramics. How is pottery made? First, a potter takes some clay. Clay is a soft, red material from the earth. It looks a little like red dirt, but it's very different. Clay is thick and rich. Wet clay can be worked into any shape. When the clay dries, it will keep that shape. The potters takes some clay and pushes and squeezes it until it is soft and smooth. After that, the clay can be shaped into anything. There are several ways to shape clay. Sometimes potters use their hands. Sometimes they use a special wheel. They place the clay in the center of a round, flat wheel. The wheel moves very fast, and the potter shapes the clay. After the potter has shaped the clay, it can be decorated . Potters use glaze, which is a kind of paint, to decorate their work. Some glazes are very simple. Other glazes have beautiful colors and designs. The glaze is not just beautiful. It is also useful. The glaze makes the pottery smooth and waterproof. Potters also make some decorative lines and designs on the surface. After it is decorated, the clay must be baked, or fired, in a special oven. Baking the clay at very high temperature makes it hard and strong. Firing also makes the glaze stick to the pottery. When the firing is over, the potter carefully removes the pottery from the oven and lets it cool slowly. If it cools too quickly, it could crack and break. Since pottery is waterproof, it is very popular for dishes. You can find examples of pottery in almost any home. But pottery can also be found in museums. Some pieces of pottery are valuable and beautiful pieces of art.

[EX Q]: Article: Davey wanted to play baseball. But fifty years ago, in his small town, he couldn't find enough players for two full teams or an empty lot big enough for a field. And when he played ball in his back yard, he just broke windows and got into trouble. So Davey began playing with a plastic golf ball and a broom handle for a bat. When his dad, David Mullaney, a former semi-pro baseball pitcher , realized his son was hurting his arm trying to throw curves with the little plastic ball, he decided to find a better solution. Mullaney got a bunch of hollow plastic _ from a local factory, sat down at his kitchen table and began cutting different size holes in the balls with a razor knife. He thought maybe the holes would alter the ball's flight and help his son throw curves and sliders without hurting his arm. All the balls failed--except the one with the eight oblong  holes cut into one of the hemispheres. This ball curved naturally and sharply without a violent snap of the wrist. In fact, Davey was now striking out so many batters; he called his new ball a "wiffle ball". A year later, Mullaney borrowed $20,000 from family and friends and started producing Wiffle Balls in his little suburban town of Shelton, Connecticut. "I didn't want investors." He said, "I wanted to control my own company." This was the beginning of one of the hottest fads  of the fifties and a perennial  best seller well known all around the world. Since then millions of boys and girls have enjoyed countless hours of safe, wholesome fun playing with a Wiffle ball and bat. Esquire Magazine has even called the Wiffle Ball "a national treasure". By producing a high quality product at an affordable price, three generations of Mullany's have enjoyed the satisfaction and benefits of running a successful and profitable family business. Over the years, they've had plenty of offers to buy them out, but they're still working out of a small factory in Shelton, making a new Wiffle Ball every couple of seconds. Creativity and persistence are two of the important sources for wealth. If he gave up his attempts at trying new things, Mullany would not have invented the wiffle ball, nor would he have made such a big fortune.
